The new ShareActionProvider available in Android 4.0 (or in earlier versions if you\'re using ActionBarSherlock) has a feature where the last used item is displayed in the a
Point of clarification: It's not the "last used", it's "most often used", across a sliding window period of time.
If you prefer not to use history, then before creating your views, call
yourShareActionProvider.setShareHistoryFileName(null);
Description of this method, from the official docs (emphasis mine):
Sets the file name of a file for persisting the share history which history will be used for ordering share targets. This file will be used for all view created by onCreateActionView(). Defaults to DEFAULT_SHARE_HISTORY_FILE_NAME. Set to null if share history should not be persisted between sessions.
EDIT: I should clarify — The "most often used" item won't show up if there's no history, so this is currently the only way of removing that button.
